Quick Details Payment Terms: T/T,Western Union,MoneyGram Supply Ability: 10.0 Kilogram/Kilograms per Month Other Names: alpha Amylase EINECS No.: 232-565-6 Classification: General Reagents Purity: 99% MF: / Appearance: yellow brown powder CAS No.: 9000-90-2 Packaging Detail: aluminum foil bag Product Description  BR 4000u/g alpha Amylase (Bacilus subtitles )CAS 9000-90-2      Enzyme activity definition: 1g enzyme powder is expressed in grams of liquefied soluble starch in 1 hour at 60℃ and pH 6.0 Thermal stability: It is relatively stable below 60℃, and the optimum temperature is 60-70℃, which can be applied to the liquefaction process up to 90℃. PH stability: It is relatively stable at pH 6.0-7.0, the most suitable pH is 6.0, and the inactivation is serious below pH 5.0.The effect of calcium ion concentration on enzyme activity: calcium ion can improve the stability of enzyme activity, without calcium ion, enzyme activity is completely lost. Introduction: It can hydrolyze the α -1.4 glucosidic bond in the starch molecule, arbitrarily cut short-chain dextrins of varying lengths and a small amount of low-molecular-weight sugars, and both amylose and amylopectin are decomposed in an irregular form. So that the viscosity of the starch paste drops rapidly, that is, "liquefaction", so it is also […]
